The purpose of thisinventionzisto provide certain improvements infabricated iprops or shoring for elevated structures; Thegpresent I invention I relates to fabricated" shoring or temporary supporting means: forjplas'tically formed elevatedstructures; said shoring being readilygfo'rmed -or assembled from rela tively inexpensive-and {extremely light mate- ,rial". and [adapted to support an equal or.

greater-1 weight than 'jsolid shoring having a far greater volume :ofsimilar? material therein. Y

In J the :past, [shoring of this: general character has: been unwieldyand difficult to I handle due to its weight-and size Also, such cumbersome shoring necessitated the expen-- diture of muchundesirable labor by an ob jectionably large -number of workers, and,in

many cases, if made of wood, was wholly destroyed upon removal;

' This invention is designed to overcome the above noted as well i as other" defects and objections in the provision-of'fabricated shoring requiring comparatively lesslabor to cut to the desired size and assemble in the desired location and manner. l

The invention also seeks to provide shoring or supports which are lighter in weight than the previously used wooden oristeel shoring, and inwhich a far less-volume of material will support an'equal or greater weight'than the same'material v usedzin formertypes or styles :of'temporary supports.- I I It is also animportant Object'ofthisinvention to provide simple and ea'sy means for; assembling and adj usting, the elements of the fabricated shoring. 7 i While some of themore 'salient featuresand characteristics of structures embodying this invention have been set forth above, others will become apparent from thefollow-= ing disclosures. r The invention includes-these. andJother fea-. tures ofconstruction and combinations of parts hereinafter described and shown in a preferred form :in the; drawings as more par-v: ticularly indicatedby the. claims.

mule illustrated embodiment oriuus in- 5 i vention a' T' shore is shown standing upon a'floor orz base B and comprising avertical portion 14 of-novel construction as will hereinafter more fully appear and a similarly v constructed beam or horizontal member '15 M positioned transversely to the upright 14; and resting thereupon; As shown more" clearly inFig'ure 1,the T-shore supports, in this instance, an overhead structure 16' formed of plasticamaterialflThe usual steel arch 17,

together with a plate=18 having oppositely disposed wings 19 andi20 thereon, supports theplasticmateri-alalti untilrthe same becomes $613.1. 1 i t i The upright 14; is formed withaplurality, m0

ill

For example, it four such supports 21 are cut from a piece of lumber commonly termed a2.X '4? andpositioned. as shown in the drawings, they will form an upright of sub stantially the same dimensions and capable of withstanding at least the same pressure as a 4" X 4". Gbviously, in most instances an upright so formed will withstand greater ressure'than asolid 4" 4" and of course" 7 9 since there is far less (material in such construction the upright 1s easier to 'han'dleand to cut to a desiredsize than a solid support of the same exterlor dimensions.

Of course, the bars or supports 21 must be rigidly held in their operative position andto accomplish this, inter engagcable clips 22 and 23 are provided. The clips22 and 23 are substantially alike except that the central portion'sare split in opposite directions, which renders the clips interengageable to form substantially asingle connecting unit for the bars 21. These connecting units, of course, are spaced at various intervals along the upright 14' whenever necessary to adequately maintain the members 21 in their use i'ul form.

Each of the clips comprises a body portion 24 which is slit substantially halfway through as at 25 so that when the second clip similarly but oppositely slit is engaged therewith, a connecting unit will be formed of substantially the same thickness or height throughout. The ends of thebody portion 24 are doubly slit to provide triple tongues thereon. It is apparent that if so desired the adjacent edges of the tongues when the same are cut may be shaven or a thin strip removed to facilitate the bending and handling of the tongues. The outer tongues 26 are bent at right angles to the body portion 24 and the central tongue 27 is also bent at right angles to the body portion but oppositely to the tongues 26. These tongues are so bent that the outer tongues 26 on one end of the body portion will be in alignment with an inner tongue 27 on the other end of the body portion, thereby equalizing the stress to which the clip is subjected. Obviously the clips are ofresilient material and, if so desired, may be substantially straightened when removed from a support, and the tongues rebent when a new support is formed.

All of the tongues are apertured as at 28, to permit the easy tacking of the same to the supporting bars 21 by the nails 29. When may bejoined together and adjusted to corre.

spend with the extra high structure. To join the sections of an upright 14, a'core 31 is inserted in the central hollow of the upright sections, which core substantially fills the hollow as ,clearly'shown in Figure 7 As shown in Figure 8 this core31, if so; desired, may be madefup'of short piecies21a of the supporting bars21 positioned with their longer sides outwardly so as to fill the central opening. .Of course, the sections of the upright 14 are slidable over thecore' 31 and when so adj ustedto their desired height, they are held in spaced relationship by a plurality of short members 32. tacked to the coreby nails 33.-

These short'members '32 are; merely cut-off In the case of an unusually portions of the bars 21andare similarly p0 sitioned about the core 31. Since the core projecting within the upright sections adj acent the members 32 prohibits the use of clips 22;and 23, thesup'port-ing bars 21 are secured in thisregion by bands at 34 .orequivalent 1neans. i

The connecting or coupling means just above described act substantially-as a coarse adjustment "for the length of the upright 14, but due to the quickness with which the upright'is formed there is danger of a slight variation-from thedesired. length. To compensate forthis slight variation a fine adjustment is'provided which consists of a pair of oppositely disposed wedge-shaped blocks 35 and 36 in juxtaposed relationship and disposed between the base of the upright and the floor 13. The height of the upright 14 may be slightly varied by blows upon the block 35 and 36'to insure the tighter abutment of the upright with the overhead structure to be supported. 3

The cross beam 15 is formedin substantially. the same manner as the upright 14, although in most cases it is preferably to have the cross-section of the beam 15 rectangular instead of square. This'is accomplished by a slight change of the corner bars 37, namely, so that they have a relatlvely elongated triangular CI'OSS-SGCtlOIILS clearly shown in Fig- .ure 1 and the use of relatively elongated clips corners of theb'ars 37 used for a cross beam 15,

are cut-ofi" as shown at'38 in Figure'l, thereby providing a better abutment surface if the bars are pressed into contact with each other in regions between the clips 22a and 23a. Of

course, if so desired,.the corners of the trian vgular bars 21 may be cut-off in the same manher as shown at 39 in Figure 6, and it is obvious too that the uprights or beams may be of square or rectangular cross-section 1n; ac-

cordance with convenience and suitability.

The plates 19 with their oppositely disposed wings are usually provided in short sections which are slid'ably interengageable as shown inFigure 9. .These plates are apertured as at 40. The usual wires or ring-bolts 41 are imbedded in the plastic material 16 and project downwardly therefrom through'cer '20 tain of the apertures 40 and through the spaces (corresponding to the space 30 of Figure 1) betweenthe bars 37. of the beam 15 and extend slightlyinto the interior ofthe upright 14. Nails 42 aresimilarly 'imbedded in thematerial 16 and extend through other of the apertures 40. The upper corner bars 87 of the beam 15 are secured to these nails 42; After the plastic material 16 is set or hardened andthe uprights 14 and beams 15 have been removed the wires 41and nails 42 act as furring for lathing, ceiling or the like.

Figures 11 and 12 illustrate the manner in which the present invention is used for supporting the overhead structures having a relatively wide projection of plastic material 16a thereon, necessitating the use of two beams 15 thereunder. In this case, a suitable cross beam 43 of any desired kind, is interposed between the beams 15 and upright 14, whereby only one upright is necessary to support the two cross beams 15 at a given point. As shown in Figures 11 and 12 a Z-iron 44 may be used instead of the plates 19. These Z-irons also come in short sections, which are slidably interengageable and they too are apertured for the projection of furring means therethrough. As shown in Figure 11 the overhead structure may be support-ed between the projections 16a, by cross beams 15a'similar to cross beams 15 but disposed upon a higher plane.

It is to be noted that in the use of this invention it is preferable to use a cap 45 or its equivalent to embrace the ends of the upright 14 and cross beams 15 to stability of the same.

From theforegoing it is'apparent that I have provided fabricated shoring which is light in weight, easy to handle, readily assembled, and formed of inexpensive parts that maybe ordered and delivered to the desired location ready for use and necessitating only the work of cutting them to the desiredlen th.
